Ecology
Rat King is a magical creature outside the normal ecological taxonomy — too constructed to be a beast, too natural to be an aberration. It is most often found in ruins regions. It is medium-sized, which shapes how it hunts, hides, or fights.
Behaviour
Rat King is territorial and aggressive; rarely capable of negotiation in any meaningful way. Its Chaotic Evil alignment shapes how it engages with the world — predictable in tendency, even when unpredictable in detail. It is largely instinct-driven; complex strategy is the work of whoever (or whatever) commands it.
Origin
Rat King is introduced in Kobold Press's Tome of Beasts 1 (2016). Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
